This articulator was very popular during the last half of the 19th century. It was touted to be the first one invented that dispensed with the removable joint pin, a part that was so easily lost or mislaid. It was also said to be capable of all motions required in an articulator and could be brought back to centric position with ease and certainty. The joint mechanism was "self-locking." The price remained at $2.50 for thirty years.
